Materials Data on K6Sb14Se6O25 by Materials Project
Abstract
K6Sb12O25(SbSe3)2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of two SbSe3 clusters and one K6Sb12O25 ribbon oriented in the (1, 0, 0) direction. In each SbSe3 cluster, Sb4+ is bonded in a trigonal non-coplanar geometry to three Se2- atoms. All Sb–Se bond lengths are 2.54 Å. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a distorted single-bond geometry to one Sb4+ atom. In the second Se2- site, Se2- is bonded in a single-bond geometry to one Sb4+ atom. In the third Se2- site, Se2- is bonded in a distorted single-bond geometry to one Sb4+ atom. In the K6Sb12O25 ribbon, there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.77–3.42 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.77–3.41 Å. In the third K1+ site, K1+ is bonded in a 9-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging frommore »
